Answer:
and 
Step-by-step explanation:
Given:
.......................... equation i
........................ equation ii
since y is equals to the two functions , we can equate the two values of y . That is , equate equation i and ii , we have
Add 
to both sides , we have
subtract 3 from both sides , we have
divide both sides by 4 , then
substitute into equation i to get the value of y , that is
Therefore :
and
Step-By-Step Explanation:
(5 + 7) + 6y
associative
because the brakets' spots changed
12 + 6y
combining
because they combined the same type of terms
6y + 12
commutative
because they changed the spots of the 2 terms

Step-by-step explanation:
$900 that he gained in December +$500 that he gained in January-$300 that he lost=$1100
We can solve this system of equations using substitution.
2y + 2x = 8
Solve for x.
2x = -2y + 8
Divide all terms by 2.
x = -y + 4
Take the equation x = -y + 4 and substitute it into the second system of equation.
2y - 4x = 2
2y - 4(-y + 4) = 2
Simplify by distributing.
2y + 4y - 16 = 2
Combine like terms.
6y - 16 = 2
6y = 18
y = 3
Now that you know the numerical value of y, substitute y with 3 in both equations to find x.
1) 2y + 2x = 8
2(3) + 2x = 8
6 + 2x = 8
2x = 2
x = 1
2) 2y - 4x = 2
2(3) - 4x = 2
6 - 4x = 2
-4x = -4
x = 1
The value of x is 1, and the value of y is 3.
Solution: B) (1, 3)
Ok so what you want to do is multiply 2 tines 4 which is 8 then multiply 723 8 times into the calculator or just press the button next to the button on the left 8 times ok then do that again for 723^5 power so whatever product you get for the both of them multiply them then divide whatever product you get on to top to the bottom oops sorry that is the long way so basically 4 times 2 is 8 now that plus 5 = 13 so now on the top half we have 723^13 and on the bottom it is the same thing so divide your answer is 1
